Summary

Duplicate Advisory: `Read` on uninitialized buffer may cause UB ('tectonic_xdv' crate)

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-qwvx-c8j7-5g75. This link is maintained to preserve external references.

Original Description

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation.

Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.

The problem was fixed in commit cdff034 by zero-initializing the buffer before passing it to a user-provided Read implementation.
